Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, specifically relating to PCB board positioning tooling. Background Technology

[0002] PCB positioning fixtures are specialized jigs or equipment used in the manufacturing, assembly, and testing of printed circuit boards to achieve precise positioning and stable fixation of PCBs. Their core objective is to solve process deviations caused by displacement and shaking during PCB processing (such as component misalignment, drilling offset, and poor contact of test probes), ensuring production accuracy and product consistency.

[0003] Currently, in the PCB manufacturing process, a large number of electronic components need to be soldered onto the PCB. At this time, positioning fixtures are needed to fix and position the PCB. In order to improve the balance of the PCB and the stability during placement, the PCB is often attached to the worktable and then fixed and positioned by clamping from both sides. However, the existing fixing method has too small a gap between the PCB and the worktable, making it very inconvenient to remove the PCB after processing. The PCB needs to be clipped up, and sometimes it can cause friction between the PCB and the worktable, which can easily damage the PCB and is not conducive to long-term use.

[0004] Therefore, it is necessary to provide PCB board positioning fixtures to address the aforementioned technical issues.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0025] like Figures 1 to 3 As shown, a PCB board positioning fixture in one embodiment of this utility model includes: a positioning worktable 1 and a positioning fixing mechanism 2. The positioning fixing mechanism 2 is mounted on the positioning worktable 1 and includes a positioning balancing component 21, a positioning power component 22, and a positioning clamping component 23. The positioning balancing component 21 is fixedly mounted on the lower side of the positioning worktable 1, the positioning power component 22 is mounted on the positioning balancing component 21, and the positioning clamping component 23 is slidably mounted on the positioning balancing component 21.

[0026] The PCB board positioning fixture is used as follows: The user controls the positioning power component 22, which in turn causes the positioning balance component 21 to operate. The positioning balance component 21 can adjust the position of the PCB board and can also be adjusted according to the size of the PCB board to fix it. At the same time, the gap between the PCB board and the positioning worktable 1 can be raised by fixing the positioning clamping component 23, making it easier to pick up and drop the PCB board.

[0027] like Figures 1 to 2As shown, the positioning and balancing assembly 21 includes: a pair of positioning and balancing mounting plates 211, a pair of positioning and balancing support rods 212, a pair of positioning and balancing fixing parts 213, and a pair of positioning and balancing limit blocks 214. The pair of positioning and balancing mounting plates 211 are fixedly installed on the lower side of the positioning worktable 1. The installation of the positioning and balancing mounting plates 211 improves the stability and balance of the positioning and balancing support rods 212, reduces the probability of tilting, and enhances the reliability of the positioning and balancing support rods 212. The pair of positioning and balancing support rods 212 are fixedly installed between the pair of positioning and balancing mounting plates 211, improving the stability of the positioning and balancing fixing parts 213, reducing the probability of tilting, allowing the positioning and balancing fixing parts 213 to slide better, improving their reliability, and making their sliding more controllable. A pair of positioning and balancing fasteners 213 are slidably mounted on a pair of positioning and balancing mounting plates 211, which can drive the sliding of the positioning clamping assembly 23, allowing for sliding displacement when the PCB board size is adjusted. A pair of positioning and balancing limit blocks 214 are fixedly mounted on both sides of the positioning and balancing fasteners 213, which can control the balance of the positioning and balancing fasteners 213 and reduce the probability of the positioning and balancing fasteners 213 tilting.

[0028] like Figures 1 to 2 As shown, the positioning and balancing support rod 212 passes through a pair of positioning and balancing fasteners 213, facilitating the sliding of the positioning and balancing fasteners 213, improving the stability of the sliding, making the sliding of the positioning and balancing fasteners 213 smoother, and enhancing the ease of sliding. A positioning and balancing bearing 215 is installed between the positioning and balancing support rod 212 and the positioning and balancing fasteners 213, reducing the friction between the positioning and balancing support rod 212 and the positioning and balancing fasteners 213, improving the stability of the sliding of the positioning and balancing fasteners 213, and making the sliding of the positioning and balancing fasteners 213 smoother.

[0029] like Figures 1 to 3 As shown, the positioning worktable 1 has a displacement groove that matches the positioning balance fixing part 213, which improves the stability of the positioning balance fixing part 213, reduces the probability of the positioning balance fixing part 213 falling off, and improves the balance of the positioning balance fixing part 213. The positioning worktable 1 also has a positioning groove that matches the positioning balance limiting block 214, which facilitates the sliding of the positioning balance limiting block 214 and makes the sliding of the positioning balance limiting block 214 more stable.

[0030] like Figures 1 to 3As shown, the positioning power assembly 22 includes: a positioning power threaded rod 221, a positioning power limiting block 222, and a positioning power friction disc 223. The positioning power threaded rod 221 is installed between a pair of positioning balance mounting plates 211. The positioning power threaded rod 221 can control the displacement of the positioning balance fixing member 213 by rotation, thereby improving the controllability of the positioning balance fixing member 213 and allowing the pair of positioning balance fixing members 213 to move closer or further apart. The positioning power limiting block 222 is fixedly installed at one end of the positioning power threaded rod 221. The positioning power limiting block 222 can limit the distance of the positioning power threaded rod 221, reducing the probability of wobbling when the positioning power threaded rod 221 rotates and improving its stability. The positioning power friction disc 223 is fixedly installed at the end of the positioning power limiting block 222 away from the positioning power threaded rod 221. The user can control the positioning power friction disc 223 to achieve the rotation of the positioning power threaded rod 221, thus improving the controllability of the rotation of the positioning power threaded rod 221.

[0031] like Figures 1 to 2 As shown, the positioning power threaded rod 221 is installed through the positioning balance mounting plate 211 and the positioning balance fixing member 213. By penetrating the positioning balance mounting plate 211 and the positioning balance fixing member 213, the positioning power threaded rod 221 improves its own balance, allowing the positioning power threaded rod 221 to rotate more stably and better drive the sliding of the positioning balance fixing member 213, thereby making the sliding of the positioning balance fixing member 213 more stable. A positioning power bearing 224 is installed between the positioning power threaded rod 221 and the positioning balance mounting plate 211, which reduces the friction between the positioning power threaded rod 221 and the positioning balance mounting plate 211, improves the smoothness of the rotation of the positioning power threaded rod 221, and reduces the damage to the positioning power threaded rod 221 caused by friction.

[0032] like Figures 1 to 2 As shown, the positioning power threaded rod 221 is matched with the positioning balance fixing part 213. When the positioning power threaded rod 221 rotates, it can drive the positioning balance fixing part 213 to move through the cooperation with the positioning balance fixing part 213, so that the pair of positioning balance fixing parts 213 can move closer to each other or further away from each other. The positioning worktable 1 has a mounting groove that matches the positioning power friction disc 223, which facilitates the installation of the positioning power friction disc 223, provides corresponding space for the installation of the positioning power friction disc 223, and facilitates the user's control of the positioning power friction disc 223.

[0033] like Figures 1 to 3As shown, the positioning clamping assembly 23 includes: a positioning clamping mounting plate 231, a positioning clamping fixing plate 232, a positioning clamping lifting rod 233, and a positioning clamping lifting spring 234. The positioning clamping mounting plate 231 is slidably mounted within the positioning balance fixing member 213. The positioning clamping mounting plate 231 can cooperate with the positioning clamping fixing plate 232 to position the PCB board, improving the fixing effect and ensuring the stability of the PCB board. The positioning clamping fixing plate 232 is fixedly mounted on the positioning balance fixing member 213. The positioning clamping fixing plate 232 can cooperate with the positioning clamping mounting plate 231 to fix the PCB board. The positioning clamping lifting rod 233 is fixedly installed on the upper side of the positioning clamping mounting plate 231. It can improve the balance of the positioning clamping mounting plate 231 and guide the positioning clamping mounting plate 231 when it is raised and lowered, making the raising and lowering of the positioning clamping mounting plate 231 more stable and reducing the probability of tilting when the positioning clamping mounting plate 231 contacts the PCB board. The positioning clamping lifting spring 234 is sleeved on the outside of the positioning clamping lifting rod 233. It can compress the positioning clamping limiting block 236 and drive the positioning clamping lifting rod 233, so that the positioning clamping lifting rod 233 can be moved upward. This allows the positioning clamping mounting plate 231 to compress the PCB board, so that the PCB board can be fixed between the positioning clamping mounting plate 231 and the positioning clamping fixing plate 232.

[0034] like Figures 1 to 3 As shown, a positioning clamping pad 235 is fixedly installed on the positioning clamping mounting plate 231, which reduces the damage to the PCB board, increases the service life of the PCB board, and reduces the probability of PCB board damage. The positioning clamping fixing plate 232 is set through the positioning balance fixing piece 213, which facilitates the sliding of the positioning clamping fixing plate 232, improves the stability of the positioning clamping mounting plate 231, and makes the lifting and lowering of the positioning clamping mounting plate 231 more stable.

[0035] like Figures 1 to 3 As shown, a positioning clamping lifting rod 233 is fixedly installed at one end away from the positioning clamping mounting plate 231 with a positioning clamping limiting block 236, which can limit the positioning clamping lifting rod 233. At the same time, it can be squeezed by the positioning clamping lifting spring 234, which can drive the positioning clamping lifting rod 233 to move. The positioning clamping lifting spring 234 is located between the positioning balance fixing member 213 and the positioning clamping limiting block 236.
